Drain Hose Routing

A drain trough encircles the sunroof glass panel and water is drained off by the drain hoses located at each corner of the housing. A drain channel spans across the sunroof module at the rear of the glass panel and directs water into the trough.
1. Verify that the front drain hoses are routed down the windshield pillars and out the center of the pillar between the door hinges. Verify that the hoses are not kinked. Replace any torn or cracked hose. Refer to Sunroof Drain Hose Replacement (Impala Rear) or Sunroof Drain Hose Replacement (Monte Carlo Rear) or Sunroof Drain Hose Replacement (Impala Front) or Sunroof Drain Hose Replacement (Monte Carlo Front).
2. Verify that the rear drain hoses are routed through the rear pillars and out of the rocker panel. Verify the rear hoses are properly routed in the metal roof slot and taped in place. Replace any torn or cracked hose. Refer to Sunroof Drain Hose Replacement (Impala Rear) or Sunroof Drain Hose Replacement (Monte Carlo Rear) or Sunroof Drain Hose Replacement (Impala Front) or Sunroof Drain Hose Replacement (Monte Carlo Front).
